Zoomlion QUY130

​The Zoomlion QUY130 is a pump-operated hydraulic crawler with a lifting capacity of 127 metric tons (140 U.S. tons).

The boom system is based on a truss-type structure, the material used for the boom sections are high strength seamless steel tubing, and individual boom sections are joined using pins. QUY130 boom extends 73m (239 ft.) and the fixed jib reaches out 31m (101 ft.), and with a maximum lift capacity of 13 metric tons (14 U.S. tons). The slewing mechanism is comprised of an internal variable displacement axial plunger hydraulic motor, gear reducer, normally closed slewing brake, pinions and slewing bearings; the pinion-driven swiveling bearing allows for full 360° movement, allowing functionality to the upper machinery. As a safety feature the slewing mechanism is lockable through a mechanical locking device located at the front of the rotating platform, ensuring complete safety during the transportation process.

The luffing mechanism incorporates a concealed dual-range type drum with an anti-reverse rotation ratchet. Also as a safety feature, the luffing winch ratchet locking mechanism prevents luffing decline when the vehicle is parked for long periods of time.

The Zoomlion QUY 130 is powered by a US Cummins electronic injection diesel engine with a CAN bus interface and a fuel oil tank holding 700L for long operating hours. Each of the two crawlers is equipped with a hydraulic motor and speed reducer set, each side can execute such traveling movements as straight line traveling, unilateral steering, differential steering, pivotal steering, driving with load, allowing it to move up to 30% grade terrain.

With safety of the machine and workers in mind, brace poles, which are of a nested steel tube and spring structure, are mounted at the base section of the main boom to provide support and to prevent the main boom from overturning. Various overflow valves in the hydraulic system suppress abnormally high pressures in the circuit, preventing damage to the hydraulic oil pump and motor, and preventing system overload. Hook safety latch prevents the load from unhooking when lifting heavy loads. In case of emergency, there is an emergency button to switch off the engine and stop all operations.
